Why here taking %6.2f instead of %f? In some times to taking %5d makes me more confusing in some texts......

Question

#include <stdio.h>

int main() {
float purchases[3] = {10.99, 14.25, 90.50};
float total = 0;
int k;

/* total the purchases */
for (k = 0; k < 3; k++) {
total += purchases[k];
}

printf("Purchases total is %6.2f\n", total);
/* Output: Purchases total is 115.74 */

return 0;
}

Answer 1

The 6 after the % means to print a minimum of 6 characters, and the 2 after %6. means 2 decimal places.
